Strange urge in me to abandon university course (7)
I believe the answer is:
regimen
'course' is the definition.
(prescribed course of treatment or diet)
'strange urge in me to abandon university' is the wordplay.
'strange' indicates anagramming the letters.
'to abandon' suggests deleting specific letters.
'university' becomes 'U' (abbreviation for university).
'urge'+'in'+'me'='urgeinme'
'urgeinme' with 'u' taken away is 'rgeinme'.
'rgeinme' is an anagram of 'REGIMEN'.
(Other definitions for regimen that I've seen before include "Disciplined system" , "Mere gin for a course of treatment" , "discipline" , "That's what doctor orders" , "Recommended course" .)
